Struct RustBuildInfo 

pub struct RustBuildInfo {
    pub rustc_version: Option<&'static str>,
    pub rust_channel: Option<&'static str>,
    pub rustc_version_full: Option<&'static str>,
}

Rust build-time information captured via build.rs.

Use emit_rustc_env in your build.rs and capture_rust_build_info! in your application code to populate this struct.

Example

In build.rs:

opentelemetry_configuration::emit_rustc_env();

In main.rs:

use opentelemetry_configuration::OtelSdkBuilder;

let _guard = OtelSdkBuilder::new()
    .service_name("my-service")
    .with_rust_build_info(opentelemetry_configuration::capture_rust_build_info!())
    .build()?;

Fields

rustc_version: Option<&'static str>

Rustc version (e.g., “1.84.0”).

rust_channel: Option<&'static str>

Rust release channel (“stable”, “beta”, “nightly”).

rustc_version_full: Option<&'static str>

Full rustc version string (e.g., “rustc 1.84.0 (9fc6b4312 2024-01-04)”).

Implementations

impl RustBuildInfo

pub fn to_key_values(&self) -> Vec<KeyValue>

Converts to OpenTelemetry KeyValue pairs for resource attributes.

Returns attributes using semantic conventions where applicable:

• process.runtime.version for rustc version
• process.runtime.description for full version string
• rust.channel for release channel
